Default intake bolts

Do I need to put lock washers on intake bolts? I bought a set of bolts from Corvette America and there were no lockwashers.

regards,
Yzordderrex

If your manifold is aluminum however, it's a good idea to use a flat washer under the bolt head. One with a smaller outside diameter than normal will give you good clearance in the tight places and stainless steel works best to prevent galling of the manifold surface.

Good luck... GUSTO

Ok. I just had manifold stripped and powder coated. I don't want to gouge up manifold.

thanks

If the bolts you have already have 'flanged' heads on them with a recessed undercut, you MAY not need lockwashers. If they are standard hex head bolts, you need lockwashers.
